    well tonight i installed some dsm 450cc injectors in a friends car. no leaks, but it idles rough, and once you hit 3500-4000rpms it stutters and loses almost all it's power. no matter if you give it half throttle or full. sounds like a freakin lawnmower.

    what seems to be the problem? would a V-AFC fix the problem? cause i have one i can hook up tomorrow if some tuning will fix the problem.

    more info on the car:
    92 civic hb
    LS/VTEC (gsr head/b18b1 block)
    short ram intake
    Skunk2 IM
    DC 4-1
    catback...
    and SKUNK2 ecu

    so what kind've settings should i set the vafc? or any other info would be appreciated.

    Thank You,
    Robbie

    you dubled the size of your injectors. its going to flood the entire time.

    i'd really like to know WHY you think he even needs bigger injecotrs? put the stock 240s back in. the mods you have don't warrant more fuel than what oem can provide
